of sand rock, above which lies eleven feet of sandy buff shales." 

 No fossils known from this horizon. 



21. Lecompton Limestone. Bennett's description : "Cap- 

 ping the hills around Lecompton is a five-foot limestone in two 

 layers, which we will provisionally name the 'Fusulina' lime- 

 stone ; not that it alone bears that fossil, but because of the 

 abundance of Fusulina in it. It is the lower of another triple 

 system [formation] of limestones, the members of which are 

 separated by a few feet of shale, and which retain this order as 

 far as observed to the west. Above the 'Fusulina' stratum are 

 five and one-half feet of clay shales, then one and one-fourth 

 feet of blue limestone, which weathers dark buff, like all its as- 

 sociate strata. Above this are four feet of shales having a 

 bituminous streak in the middle ; then ten feet of light gray, 

 easily disintegrated limestone. This group [formation] maybe 

 called the Lecompton limestone, on account of their outcropping 

 being near Lecompton. At Spencer, six miles west of Lecomp- 

 ton, the upper part of the series [formation] finally disappears 

 below the alluvial soils of the valley." 



From near the horizon of the above formation, from a well in 

 the road in the bed of Deer creek (the one emptying into Waka- 

 rusa creek ) , near the Shawnee-Douglas county line, the follow- 

 ing species have been collected : 



Fusulina secalica ( Say) . 



Campophyllum torquium Owen. 



Archasocidaris cf. agassizi Hall. 



Fenestella limbata Foerste. 



Fene stella limbata rcmota Foerste. 



Pinnatopora sp. 



Polypora distincta Ulrich ? 



Polypora elliptica Rogers ? It is quite probable that this is a 

 distinct species. It has fenestrules arranged in two intersecting 

 series when viewed on the reverse side, and the branches are 

 not striated. The fenestrules appear nearly square on account 

 of their arrangement, but in reality they are subcircular. On 

 the obverse side the nodes are very prominent and some of them 

 appear to possess acanthopores. 



Polypora cf. nodocarinata Ulrich. 



Rhomhopora lepidodendroides Meek. 



Chonotes granulifer Owen.
